String Theory on G_2 Manifolds Based on Gepner Construction
Tohru Eguchi, Yuji Sugawara
We study the type II string theories compactified on manifolds of holonomy of the type $({Calabi-Yau 3-fold} \times S^1)/\bz_2$ where sectors realized by the Gepner mo…
CFT Description of String Theory Compactified on Non-compact Manifolds with G_2 Holonomy
Tohru Eguchi, Yuji Sugawara
We construct modular invariant partition functions for strings propagating on non-compact manifolds of G_2 holonomy. Our amplitudes involve a pair of N=1 minimal models M_m, M_{m+2…
Boundary States of D-branes in AdS_3 Based on Discrete Series
Yasuaki Hikida, Yuji Sugawara
We study D-branes in the Lorentzian AdS_3 background from the viewpoint of boundary states, emphasizing the role of open-closed duality in string theory. Employing the world sheet…
Formation of Spherical D2-brane from Multiple D0-branes
Yasuaki Hikida, Masatoshi Nozaki, Yuji Sugawara
We study D-branes in SU(2) WZW model by means of the boundary state techniques. We realize the ``fuzzy sphere'' configuration of multiple D0-branes as the boundary state with the i…
